Low vitamin D levels linked to premature death

People with low levels of vitamin D may be at increased risk of premature death, according to a new study from the University of California-San Diego School of Medicine.

Scientists reviewed 32 studies that analyzed the relationship between vitamin D, blood levels and mortality rates of more than 566,000 adults with an average age of 55 from 14 countries. Specifically, they assessed levels of 25-hydroxyvitamin D, which is the main form of vitamin D found in human blood.

The researchers found that people with lower levels of vitamin D in their blood were twice as likely to die prematurely, when compared with people with higher levels. They specifically found that the vitamin D blood level of 30 ng/ml or below was the number associated with risk of early death, which researchers said was significant in that approximately two-thirds of Americans are currently below this level.

The study’s findings, published in the American Journal of Public Health, suggest that people should have their vitamin D blood levels checked annually as a preventive measure. The researchers added that patients should consult their doctor before adjusting their vitamin D intake.
